Abstract EN

Competencies assessments are complex situations for assessing students' performance using tasks, raters, occasions and assessment methods.

This can affect student scores and decrease their generalizability.

Based on Generalizability theory, research showed that reliability and validity of competency assessments are influenced by sources of error especially due to raters, tasks, person-task interaction, occasions and assessment methods.

This article deals with a review of research literature used Generalizability theory in examining the sources of error that affect reliability and validity of competency assessments, and provide the ways to reduce each source of error variance on dependability of scores.
